The development of language in genie: a case of language acquisition beyond the “critical period”

The present paper reports on a case of a now-16-year-old girl who for most of her life suffered an extreme degree of social isolation and experiential deprivation. It summarizes her language acquisition which is occurring past the hypothesized “critical period” and the implications of this language development as related to hemispheric maturation and the development of lateralization. The results of a series of dichotic listening tests administered to her are included.     

Misalignment and Misperception in Preferences to Utilize Family‐Friendly Benefits: Implications for Benefit Utilization and Work–Family Conflict

Despite their increasing popularity, family‐friendly benefits are frequently underutilized. Drawing on literatures concerning social norms and pluralistic ignorance, this study examines the role of personal preference, group norm misalignment, and misperception of group norms on employees’ utilization of family‐friendly benefits. In 2 samples (154 firefighters and 440 nurses) across 3 data collection periods, we found that when employees’ preferences for benefit utilization were misaligned with the perceived group norm, they adjusted their family‐friendly benefit utilization in a manner congruent with the norm, even when that norm was misperceived. Further, we found that family‐friendly benefit utilization was negatively associated with work–family conflict. Together, our findings suggest that misperceived social norms regarding family‐friendly benefit utilization can lead to situations whereby employees do not utilize family‐friendly benefits because they mistakenly perceive utilization is not socially accepted and, as a result, experience higher work–family conflict.     

The prematurity stereotype revisited: Impact on mothers' interactions with premature and full‐term infants

Research exploring the effects of labeling on maternal perceptions and behaviors was extended by simultaneously examining the cognitive and behavioral effects of prematurity stereotyping with both mothers of full‐term and premature infants, and by examining the effects of an information‐based intervention on the stereotyped responses of mothers of premature infants. An experimental design wherein mothers of both full‐term and premature infants were randomly assigned to interact with, and then rate, either a full‐term or premature infant who was described as either full‐term or premature was employed to test several hypotheses. Two hypotheses related to prematurity stereotyping received support: mothers showed more positive responses to infants labeled full‐term than to infants labeled premature, and mothers of full‐term infants exhibited more prematurity stereotyping than did mothers of premature infants. The hypothesis concerning gender effects also was supported, with mothers showing more positive responses to male infants than to female infants. In contrast to expectations, a brief cognitive intervention provided to some mothers of premature infants failed to reduce stereotyping, and, indeed, appeared to increase stereotyping. These results are compared with the results of previous studies, most of which did not include actual interactions between mothers and infants, and the implications of these results are considered. © 2000 Michigan Association for Infant Mental Health.     

Children's biobehavioral reactivity to challenge predicts DNA methylation in adolescence and emerging adulthood

A growing body of research has documented associations between adverse childhood environments and DNA methylation, highlighting epigenetic processes as potential mechanisms through which early external contexts influence health across the life course. The present study tested a complementary hypothesis: indicators of children's early internal, biological, and behavioral responses to stressful challenges may also be linked to stable patterns of DNA methylation later in life. Children's autonomic nervous system reactivity, temperament, and mental health symptoms were prospectively assessed from infancy through early childhood, and principal components analysis (PCA) was applied to derive composites of biological and behavioral reactivity. Buccal epithelial cells were collected from participants at 15 and 18 years of age. Findings revealed an association between early life biobehavioral inhibition/disinhibition and DNA methylation across many genes. Notably, reactive, inhibited children were found to have decreased DNA methylation of the DLX5 and IGF2 genes at both time points, as compared to non‐reactive, disinhibited children. Results of the present study are provisional but suggest that the gene's profile of DNA methylation may constitute a biomarker of normative or potentially pathological differences in reactivity. Overall, findings provide a foundation for future research to explore relations among epigenetic processes and differences in both individual‐level biobehavioral risk and qualities of the early, external childhood environment.     

Hope as empowerment model: A client-based perspective on the process of hope development

Abstract

Research on the relationship of client hope to successful therapy outcome underlines the need to discover the processes and conditions when hope flourishes. Snyder’s Hope Theory has been applied to psychotherapy but client subjective experiences are needed to illuminate nuances in the process. The present study examined the trajectory of hope development in psychotherapy using interviews with 18 counseling clients, analyzed using grounded theory methodology. Findings were synthesized into a dynamic model titled hope as empowerment model (HEM) that shares features of Snyder’s Hope Theory. HEM introduces patterns of particular salience to psychotherapy. The compatibility of client preferences with therapist input raised faith in the process of counseling and, in turn, hope in a positive outcome. A number of conditions, including the flexibility of client role preferences and the directiveness of hope-inspiring therapeutic strategies, influenced the nature and strength of client hope. Implications for therapy and positive psychology are considered.     

Dynamics of Word Comprehension in Infancy: Developments in Timing, Accuracy, and Resistance to Acoustic Degradation

Online comprehension of naturally spoken and perceptually degraded words was assessed in 95 children ages 12 to 31 months. The time course of word recognition was measured by monitoring eye movements as children looked at pictures while listening to familiar target words presented in unaltered, time-compressed, and low-pass-filtered forms. Success in word recognition varied with age and level of vocabulary development, and with the perceptual integrity of the word. Recognition was best overall for unaltered words, lower for time-compressed words, and significantly lower in low-pass-filtered words. Reaction times were fastest in compressed, followed by unaltered and filtered words. Results showed that children were able to recognize familiar words in challenging conditions and that productive vocabulary size was more sensitive than chronological age as a predictor of children's accuracy and speed in word recognition.     

Structure and measurement of depression in youths: applying item response theory to clinical data

Our goals in this article were to use item response theory (IRT) to assess the relation of depressive symptoms to the underlying dimension of depression and to demonstrate how IRT-based measurement strategies can yield more reliable data about depression severity than conventional symptom counts. Participants were 3,403 children and adolescents from 12 contributing clinical and nonclinical samples; all participants had received the Kiddie Schedule of Affective Disorders and Schizophrenia for School-Aged Children. Results revealed that some symptoms reflected higher levels of depression and were more discriminating than others. Furthermore, use of IRT-based information about symptom severity and discriminability in the measurement of depression severity was shown to reduce measurement error and increase measurement fidelity.
